“In houses we find many species that are cosmopolitical, and they have moved with people all around the world. We commonly find some of the jumping spiders feeding on flies and cockroaches, the spitting spiders feeding on booklice, ant-eaters feeding on ants, rain spiders feeding on moths, the daddy long legs feeding on ants and the brown button spiders feeding on bugs. The only problem species in houses is the sac spider and in a few areas violin spiders.”
